Even though it made Lin Yujing feel uncomfortable, Yu Hong's praise did not stop.

"Lin Yujing, don't be embarrassed. What the teacher said is not an exaggeration at all."

"This time, let's talk about the monthly exam papers in a different way."

"Classmate Lin Yujing, who received full marks, will explain it to everyone."

"I hope you can listen."

"Especially for students who work hard but get poor grades, try it and see if you can get any inspiration."

Yu Hong said, stepped aside, and raised his hand to invite Lin Yujing to come on stage.

Lin Yujing lectures?

It's busy at get off work now.

Lin Yujing, however, kept shaking her head.

Seeing this, Jiang Qinghua took the lead in applauding: "Come on Yu Jing, the teacher has asked you to do it."

The classmates also followed suit and clapped.

"Seek study and God's teachings."

"The future professor of Chemistry Department of Ji University is here!"

Even Liu Xin applauded wildly.

As long as it looks good, that’s it, no matter what you say.

Seeing Lin Yujing shrinking in shame, Li Zheng snorted and smiled.

He knows Lin Yujing.

impossible.

It is impossible for such people to share their learning ideas.

Sure enough, Lin Yujing half-hidden her face and raised her hands and said: "Teacher Yu... I feel uncomfortable in my throat..."

"Ah, really..." Yu Hong came back on stage a little disappointed, "Let's do it next time."

The classmates were also disappointed.

It’s time to listen and reread again.

Only Jiang Qinghua's expression brightened, and he lowered his head and risked taking out his mobile phone to start operating.

Yu Hong began to speak.

Li Zheng also laid out the papers and listened to them one by one.

After studying for more than twenty hours continuously, this paper seems to be no longer worth mentioning.

Looking at his mistakes, he even blushed with embarrassment, as if he was looking at a retarded person.

While the teacher was explaining the questions, he was also re-doing the questions he got wrong and writing the answers he understood now next to them to test his learning results.

Li Zheng was able to correct most of the wrong questions almost immediately. Even at a normal learning rate, it only took a few minutes to correct all the mistakes.

He felt a smoothness that he had never experienced before.

It's not the clear thinking of physics and mathematics, but the smoothness of Chinese and English.

This kind of integration is difficult to describe in words.

It turns out that all this time has been accumulating.

At this point, I barely touched the threshold of chemistry.

Even so, he still didn't fully understand the seventh question.

It just so happened that Yu Hong also talked about it here.

"Let's look at the seventh question. It's the only question Liu Xin got right. I'll give you points."

"Which of the following statements is incorrect?"

"[a, sucrose, fructose and maltose are all disaccharides.]"

"I learned from the beginning that fructose is a simple sugar, so statement a is wrong, choose a."

"Because it is a multiple-choice question, in order to save time during the exam, there is no need to read b, c, and d at all."

"But we still have to say something here."

"[b, Enzyme is a type of protein with catalytic properties.]

"This description is correct. I won't say much more. It's in the textbook."

"[c, Different crops have different optimal growth pH ranges.]"

"Even if you don't read the textbook, common sense should know that this is right."

"[d, Industrial electroplating has certain requirements for the pH of the plating solution.]"

"I'm afraid that you won't be able to get the free points, so I specifically chose option D, which everyone knows is fine,"

"A certain classmate has lived up to expectations."

"To sum up, b, c, and d are completely correct, and a is obviously wrong, so I choose a."

Amidst the laughter, Liu Xin scratched his head again.

After finally answering one question correctly, can this be targeted?

"But!" Yu Hong suddenly changed the subject and looked at Li Zheng, "There is a classmate in our class who always works hard, but he gave a funny answer. Li Zheng, tell yourself, what did you fill in?"

"a, b." Li Zheng replied.

"You are really awesome. You have been writing papers for more than a year. I wonder if this is a multiple-choice question?"

"Based on your answer, I really don't know how hard you usually work."

Sparse laughter sounded.

Liu Yue even stretched her neck to watch the joke from a distance.

"Teacher, Li Zheng has memorized all the books."

For a while, there was a lot of discussion.

Occasionally, some people show a look of superior intelligence.

"Studying to death is still not enough."

"Li Zheng is stupid, he has multiple choices..."

"I didn't even study, but I answered all these questions correctly, haha."

Being looked at like this by the whole class.

Li Zheng is not bad either.

The only thing I don’t want is Lin Yujing...

He couldn't help but secretly squint his eyes and observe from the corner of his eye.

It's strange that Lin Yujing didn't laugh at such a good opportunity.

On the contrary, she ignored Li Zheng at all and was flipping through the book nervously.

On the podium, Yu Hong sighed repeatedly.

"Hey...do I want you to memorize it?"

"Understanding, the key is understanding."

"Li Zheng, ask Lin Yujing, did she carry it?"

"Tell me, where in the chemistry book does it say that enzymes are not proteins?"

"I didn't say it." Li Zheng nodded. "The description on page 81 of the textbook is 'Enzymes are a special type of protein and are important catalysts in living organisms.'"

"Look, although your eyesight is bad, your memory is very good." Yu Hong raised his head and asked, "It's written like this in the book, why do you still choose B?"

"Because the description in the chemistry book conflicts with the description in the high school biology book." Li Zheng explained, "The chemistry book says that enzymes are a type of protein, but the biology book says that most enzymes are proteins, and a few

for RNA.”

"For this reason, I worked very hard to get it on Wikipedia."

"After checking, the description in Wikipedia is consistent with the biology textbook."

"Afraid of omissions, I clicked on more entries to double-check."

"Cech discovered ribozyme in 1981 and won the Nobel Prize in 1989."

"In addition, mainstream articles on Zhihu and CNKI also clearly stated that the enzyme may also be RNA."

"Other new editions of chemistry textbooks also use the above statement."

"At this point, it is basically confirmed that the version of the chemistry textbook selected by our school has an incorrect description."
